Blocking Facetime application

Blocking Apple's Facetime app can be problematic. Even with SSL Inspector enabled, Application Control will only see Facetime as a generic "APPLE" application. The most effective way to block Facetime is to block port 5223 in Firewall. Facetime uses ports 53, 80, 443, 5223, and 16393-16472 (UDP), but blocking 5223 will prevent calls from going though.
